thanks for taking the time to read this and with my question is i am looking for reservoir cap to put the antifreeze in, i am stomped, it is not like a normal car where the cap is on the radiator, please help
take another look under the hood and locate a reservoir that is off to the side // it probably looks to be the canister for the windshield washer and if you plan to add antifreeze why ... if you vehicle is running hot then you need more than just adding fluid. RETHINK what you are doing and go to the closest garage and get it checked by a mechanic before you burn up the engine... it is cheaper to pay a mechanic to help you than to have to replace the motor or the whole auto. Not being to see the car this is the best advice that I can give.. if you got a light indicating engine '''check''' then it is a problem because Cadillac has one of the best on/board computer systems and it is there to protect you and the car
